Striving to make a difference in the field of biodiversity conservation, Dr Katlego Mashiane decided to pursue a PhD in Geography, focusing on the spatial modelling of grassland diversity and nutrients in subalpine environments. He received his PhD during the recent April graduation ceremonies on the Qwaqwa Campus.

In the small village of Ga-Mabotia about 25 km outside of Polokwane, Dr Katlego Mashiane grew up, surrounded by rocky mountains characterised by boulder outcrops, where he interacted with nature from an early age. 

He recently obtained his PhD, majoring in Geography, from the University of the Free State (UFS), which was conferred on him during the April graduation ceremonies that took place on the UFS Qwaqwa Campus. The title of his dissertation is Grass nutrients estimation as an Indicator of rangeland quality using satellite remote.

Predicting the presence of biodiversity and nutrients in an area

Based on the principle that diverse grasslands tend to perform better, environmental changes threaten the resilience and services these grassland ecosystems provide. The study examined how many different types of plants and animals can be found at a particular place to enhance our understanding of the ecosystem’s value to humans, and that biodiversity loss will reduce these ecosystem services. Focusing on spatial modelling of grassland diversity, Dr Mashiane specifically investigated the influence of topography and remotely sensed satellite data on species richness and diversity in subalpine environments, and how they are affected by the availability of grass species. To determine this, he used a random forest machine-learning algorithm to find the best information in the data that could be used to estimate the levels of species richness, diversity, and nitrogen in a protected national conservation park. 

His study discovered that some data types – such as the near-infrared variable and certain vegetation data (EVI and SAVI) – were especially useful for determining the number and variety of species in a certain area. With this information, scientists can create models that predict the presence of different types of biodiversity and nutrients in an area.

Playing a key role in protecting our natural assets

Equipped with this knowledge, one will be able to understand how to protect and preserve different types of biodiversity and promote the nutritional value of both plants and animals in the environment. “Land managers could use this information for conservation strategies,” states Dr Mashiane, who decided to pursue this study because he was curious about how environmental changes will affect species.

“Grasslands provide important ecosystem services underpinning human well-being, and therefore warrant our protection; I would like to play a role in protecting our natural assets and contribute to understanding our biomes, especially in the context of global change,” he says.

In the next five years, Dr Mashiane plans to pursue further research and mentor other students in his field of study.

Ten young musicians from the Odeion School of Music (OSM) will travel to Europe later this year after being selected as members of the 2012 Miagi Youth Symphony Orchestra.

These talented musicians will play at venues in Germany and Austria in July 2012. As part of the Miagi Youth Symphony Orchestra, they will share the stage with some of the best youth orchestras from around the world. On the orchestra’s itinerary is a performance at the Young Euro Classic Festival in Germany where they are scheduled to perform at the opening concert. The Young Euro Classic is the world’s premier festival for symphonic youth orchestras. Before their trip to Europe, the Miagi Youth Orchestra will play at a farewell concert at the Linder Auditorium in Johannesburg.

The Miagi Youth Orchestra operates under the auspices of a non-profit organisation MIAGI (Music Is A Great Investment). The organisation covers all costs of the European tour.

Ms Ingrid Hedlund, Creative Manager of Miagi, says 88 young musicians have been selected for the 2012 events and tour of Europe. She finds the level of talent of the students studying at the Odeion School of Music very high. That is why so many students from the OSM were selected to play in the orchestra.
